DZG Series gas fired Steam Generator
For large and medium-sized enterprises which do not have heat supply from the central thermal power plant, when the continuous and stable steam consumption is above 20t/h, there are generally conditions for the establishment of self-provided thermal power plants. This kind of enterprise can choose 20t/h medium pressure boiler type or 35t/h medium pressure and sub-high pressure boiler, 1.5MW or 3MW back pressure type steam turbine-generator set, and build self-provided thermal power plant, which is mainly heating and auxiliary to generate electricity, and can obtain great economic benefits. Compared with the dispersed small-scale industrial boiler, the fuel consumption of the cogeneration is equal to that of the small-scale boiler due to the higher thermal efficiency of the boiler. Under the same heating conditions, it can be obtained by using co-generation of heat and power. Extra power.
Thermal power plant boilers provide steam to turbine generator, including boiler and ancillary equipment. The fuel in the boiler furnace release heat energy after combustion, so that the heat be transferred to water in the boiler through the metal wall into the superheated steam with a certain pressure and temperature, and then fed the steam to turbine, the steam turbine drive generator to generate power.
Select natural gas boiler when security issues are important natural gas heating boiler is to protect human health and indoor warm, so the choice of natural gas boiler when security issues are important, but the quality can not be ignored, and only with good quality, was more at ease when in use, some services also can do better, choice of heating is customer satisfaction. Learn natural gas boiler certainly need to know the sales of the product, and if it shows good reputation natural gas boiler in the comprehensive aspects are still very good, worthy of consumer choice, performance, and thermal energy conversion can consult, when such use was not there will be problems when installed, do not worry voltage is not enough. Gas boiler shutdown method: after stopping a powder, a duct for 5 minutes and then purged to stop the gun. Oil gun should be purged one by one, not at the same time purging multivessel oil gun. After completion of purging gun oil, natural ventilation of the boiler furnace 5 to 8 minutes, 20 ~ 30% of the air volume is not less than the rated load. To exclude combustible material remaining in the furnace. Different power ratings differ dzg series fired steam generator relief valve, the rated steam pressure less than or equal to 3.82MPa steam generator valve throat diameter of not less than 25mm; the rated steam pressure is greater than 3.82MPa boiler safety valve throat diameter of not less than 20mm; pipe connecting the boiler safety valve, which cross-sectional area not less than the cross-sectional area of the valve inlet. If several valves installed together with a short tube directly connected to the drum, the cross-sectional area of the passage should not step short tube to 1.25 times the area of all the exhaust valve; valve should normally be installed exhaust pipe , exhaust pipe should be through a safe place, and there is sufficient cross-sectional area to ensure the smooth flow of exhaust. The bottom of the safety valve exhaust pipe should have received a place of safety posturing of drainage pipe, the exhaust pipe and drainage pipe not allow the installation of the valve. Steam generator safety valve should meet the following requirements: Rated evaporation is greater than 0.5t h boiler /, at least two safety valves installed; equal to or less than the rated evaporation boiler 0.5t h /, mounted on at least a safety valve. The separable at the economizer outlet, the outlet of the steam generator safety valve must be installed. Valve should be mounted vertically in a high position in the pot business, set box. Between the valve and the drum or header, not equipped with access to the steam outlet pipe and a valve; lever-type safety valve should prevent the movement of the self-weight of the lever means and the limiting guides deviant, to spring safety valve there lifting handle means and preventing movement of the adjustment screw is screwed lightly.
Around at 6:00 on November 22, Guang'an City, Sichuan Province Economic Development Zone Industrial Zone, a company Newbridge burst distillation kettle explosion, the roof 20 square meters of workshop collapse occurred, had not resulted in a fire, but there are four people were injured, It has been transferred to hospital for treatment.
Suddenly the accident, the specific reasons unknown, Guang'an City, the municipal government attaches great importance to the explosion, immediately launched an emergency contingency plans, multi-power Guangan Economic Development Zone, safety supervision, environmental supervision, public security and fire protection, first time to scene to carry out rescue and subsequent disposal.
Distillation pot is directed chemical production still pot used in this step, also has a greater risk of leakage and fire accident-prone equipment. In recent years, leaking reactor, distillation kettle and other equipment, fire, explosion accidents occur frequently, mainly because often kettle equipped with a toxic, harmful hazardous chemicals, the accident consequences more serious than the general explosion, either to persons or property caused serious irreversible effects.
Distillation is one essential step in many process industries such as chemical industry, brewing, paper, food processing, it will involve the distillation process. Steam boiler equipment for the needs of enterprises to provide a distillation excellent choice. Steam boiler steam output, after a series of treatment steps of cooling, purification, extraction, etc., provides excellent quality of distilled water, for the production needs.
Fang fast has a very rich experience in R & D, manufacturing and sales of natural gas steam boilers, since practitioners, R & D and innovation has always insisted on clean fuels. One condensing gas steam boiler, gas steam boiler water, ultra-low nitrogen gas steam boiler ...... date, more than 200 kinds of types of boilers.
Over-temperature protection, over voltage protection, abnormal power protection, scale online monitoring, frost protection, the water level is too high, too low to protect and increase water protection than the traditional four fifth protection mechanism, so a series of protective measures, all-round to ensure the safety and reliability of operation of steam boilers, select the users of our products is very much at ease, peace of mind.
